if 180 is 37.5% of the whole what would be the whole

Answer:

A = 135 cm²

Step-by-step explanation:

the area (A) of a trapezium is calculated as

A = [tex]\frac{1}{2}[/tex] h (b₁ + b₂ )

where h is the perpendicular height between the bases b₁ and b₂

here h = 9 , b₁ = 19 , b₂ = 11 , then

A = [tex]\frac{1}{2}[/tex] × 9 × (19 + 11) = 4.5 × 30 = 135 cm²

In the given triangle,

sides vx and vw are equal,

and ∠v = 40°

∠w = ∠x (Adjacent angles of the equal sides of a triangle are equal)

Also, ∠v + ∠w + ∠x = 180° (Angle sum property of a triangle)

⇒ 40° + ∠x + ∠x = 180°

⇒ 2∠x = 140°

⇒∠x = 70°

Equation that can be used to represent the number of visits Violet must make to earn a free movie ticket is:

2.5v+45=75

A formula that expresses the equality of two expressions, by connecting them with the equals sign '= 'is called an equation

Unknowns are the variables for which the equation is solved and  unknown values that satisfy the equation are called solutions.

Firstly, multiply 2.5 by the number of visits (v) to calculate how many points Violet earned in total.

Now add 75 to the product of 2.5(v) because Violet started with 75 points.

To find out how many times Violet would require to visit the movie theater to get a free movie ticket:

Subtract 45 from 75,  that leaves you with 30, and after dividing that by 2.5, the number of points per visit comes out to be 12

Violet would need to visit the theater 12 times to earn a free movie ticket.

To check if that's right, substitute the value of 'v' in the equation,

Answer:

The stadium’s seating options will include premium seats (boxes closest to the action), medium-priced seats, and budget-friendly bleachers. Your design calls for 4,500 upper-deck premium seats and 7,500 lower-deck premium seats. The team’s policy is to have a 3:2 ratio of premium seats to bleacher seats. How many bleacher seats will the stadium include?

Answer: 8,000 bleacher seats. 4,500 + 7,500 premium seats = 12,000. 12,000/x = 3/2. x = 8,000.

The equation of the linear function is: 3x + y = 1.

How can we define the slope for a given line?
A line's slope in mathematics is defined as the ratio of the change in the y coordinate to the change in the x coordinate. Both the net change in the y-coordinate and the net change in the x-coordinate are denoted by y and x, respectively. Therefore, the relationship between the change in the y-coordinate and the change in the x-coordinate is provided by the formula m = change in y/change in x = Δy/Δx, where "m" is the slope of a line.
Mathematically, slope of a line = m = (y₂ - y₁)/(x₂ - x₁)
What is the y-intercept for a given line?
When a graph crosses the y-axis, that location is known as the y-intercept. It is, in other words, the value of y at x=0.
What is the general equation of a line?
The equation for a standard line is y - y₁ = m(x - x₁), where m is the slope and c is the y-intercept.

Given, the line passes through the points (-2, 7) and (2, -5).
Now, using the formula established in the literature, we get:
Slope = m = (y₂ - y₁)/(x₂ - x₁) = (-5 - 7)/(2 - (-2)) = -12/4 = -3
Equation of the linear function: y - 7 = (-3)(x - (-2)) ⇒ y - 7 = (-3)(x + 2)
⇒ y - 7 = -3x - 6 ⇒ 3x + y = 1
Thus, the equation of the linear function is: 3x + y = 1.

The missing value in the solution to the equation y = -2x+4y is y.

According to the question,

We have the following information:

y = -2x+4y

y equals minus 2 x plus 4.

Now, look at the equation, we know that the solution of y is -2x+4y.

Now, the statement that is given is incomplete because we have 4 is multiplied by y.

(More to know: this equation can be further solved. We have y = -2x+4y. Now, we can move the same variables to one side. So, we have -3y = -2x. Now, the two negative signs when divided gives the positive result.)

Hence, the statement can be completed by y.

Answer:

y = 3x + 3

Step-by-step explanation:

The slope is 3

change in y over the change in x.  As the y increases by 3, the x increases by 1.  [tex]\frac{3}{1}[/tex] = 3

Use any of the points from the table to write the equation in the slope intercept form

Let's use the first point (0,3)  Any point would give us the same answer.

We will use the x from the point which is 0 and use the y from the point which is 3.  We will also use the slope of 3.  We will plug all of these into the equation and solve for b or the y-intercept.

y = mx + b

3 = 3(0) + b

3 = 0 + b

3 = b

y = 3x + 3

The correct answer is options A and E.

f(x) = 6x + 4

f(1) = 6(1) + 4 = 10

f(2) = 6(2) + 4 = 16

f(3) = 6(3) + 4 = 22

Clearly, options A and E are the same sequences.

a. The line equation is given by:

Where m is the slope of the line and b is the y intercep.

In this case y is the number of active pilots and x is the year.

In order to obtain the line equation of the function, you use the information about a pair of years in the given table, in order to calculate the slope of the line. You can select whichever two years with its number of active pilots.

For example, for years 1980 and 1990, you have that the pilots were 182,097 and 149,666 respectively.

To calculate the slope of the line, you use the following formula:

Then, the slope of the line is negative.

If you consider the zero point of the year axis, as the year 1980, the y intercept of the function will the value of the active pilots in that years, which is 182,097.

Finally, the line equation is:

b. For the year 2003, you have that x is:

x = 2003 - 1980 =23

You replace this value of x into the linear equation:

The number of active pilots for 2003 is 107,506

The car will catch up the cyclist 3 hours after it starts moving.

The cyclist travels at 9 miles per hour, and travels for 4 hours before the car starts moving, so the equation for the position of the cyclist as a function of time, t, is:

C(t) = 9*4 + 9*t = 36 + 9*t

And the car moves at 21 miles per hour, then the position is:

P(t) = 21*t

The car will catch the cyclist when:

C(t) = P(t), this gives:

36 + 9*t = 21*t

36 = 21*t - 9*t = 12*t

36/12 = t

The actual distance between Dallas and Austin in miles is 180 miles.

Conversion of units means to convert between different units of measurement for the same quantity. Example of units are - m, cm, litre.

Given is the distance between Dallas and Austin on a map is about 9 centimeters. The map uses a scale in which 1 centimeter represents 20 miles.

The maps use scale in order to depict large distances with very small length measurements. As mentioned in the question - 1 cm represents 20 miles. This scale shrinks 20 miles of distance into 1 cm

Distance between Dallas and Austin on a map - 9 cm

On map - 1 cm = 20 miles

Therefore, 9 cm will be equivalent to (9 x 20) or 180 miles.

Hence, the actual distance between Dallas and Austin in miles is 180 miles.
